[Gauche] 途中で xmin の値が変更されてしまう。mx, my の演算に有理数を使うとこの問題が発生しない所まで確認。(0.9.2, 0.9.3.3)

	(define xmin 0)
	(define xmax 0)
	(define ymin 0)
	(define ymax 0)

	(define (f x0 y0 x1 y1 depth)

	(when (< x0 xmin) (set! xmin x0))
	(when (< x1 xmin) (set! xmin x1))
	(when (< xmax x0) (set! xmax x0))

use braille patterns for base64, instead of alphanumerics. joke.

	#!/usr/bin/env python
	#coding:utf-8

	import sys

	def base64_encode_(in_data, padding=False):
	in_len = len(in_data)
	out_data = []
	for i in range(0, in_len, 3):
	out_data.append(in_data[i] >> 2)
